What are the main aspects of the progress of handicraft production in China during the Spring and Autumn Period?

The improvement of production tools and technology and the improvement of agricultural production level have created favorable conditions for the development of handicraft industry.

First of all, handicrafts are becoming more and more specialized. During the Spring and Autumn Period, influenced by the political situation and the great development of regional economy, handicrafts in various places often have their own characteristics. For example, Wu's sword, Zheng's sword and Song's gold are all famous contemporary swords.

Secondly, a large number of emerging handicrafts have emerged. Emerging handicrafts include salt, iron smelting and lacquerware. Smelting iron is an important handicraft industry. Judging from the discovered iron smelting sites, the scale of iron smelting in the Spring and Autumn Period has been quite large, with many types and quantities of products and good quality. The ironware found in the north is mainly farm tools and hand tools, while the ironware found in the south is mostly weapons. During this period, the bronze industry still developed further, and the lotus crane square pot unearthed in Xinzheng, Henan Province represented the highest level at that time, breaking through the rigid old tradition. Chu's lacquerware is the most famous, and a series of lacquerware unearthed from Chu's tomb in Changsha during the Spring and Autumn Period are all high-value handicrafts. Qi's textile industry is very developed.
